How to import a file from outside the directory

[sylas]

I added a __init__.py in my project. I still cannot import numbers . May I have please a reply without any link.

I just put "import numbers" at the top of my solvers.py file. Apparently this import is done, but I have another error message, because he looks for a file called "numbers.csv" which is not in my project.

Error:
λ python solver.py
Traceback (most recent call last):
  File "solver.py", line 8, in <module>
    with open('numbers.csv', newline='') as csvfile:
FileNotFoundError: [Errno 2] No such file or directory: 'numbers.csv'
